title: 2-Tri-fluoro-methyl-10H-benzo[4,5]imidazo[1,2-a]pyrimidin-4-one.
abstract: In the mol-ecule of the title compound, C11H6F3N3O, the three fused rings of the benzo[4,5]imidazo[1,2-a]pyrimidine unit are essentially coplanar, the maximum deviation from the mean plane being 0.096 (2) Å. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into chains running along the b-axis direction.
